Title: Improvements in and relating to the casting of metals in permanent moulds
IPC: B22C23/02
Filed: 1926-08-05
Abstract: 256,626. Will, E. Aua. 8,1925, [Convention date]. Mould materials.-Metal moulds are given a protective coating by impregnating the surface layers of the mould cavity with metallic particles which have an affinity for the mould metal. In the case of iron moulds, zinc, bismuth or cadmium may be employed, and for copper moulds, tin. The coating metal is applied to the mould in the form of dust or vapour, and to secure sufficient penetration the coating is preferably effected in a bath at a temperature between the melting points of the coating and the mould metal. Instead of heating, high pressure may be employed. The heated mould may be further coated with a carbonaceous material. Specification 174,916 is referred to.

Abstract: 1334599 Program controlled vapour deposition ROBERT BOSCH GmbH 19 April 1971 [30 Jan 1970] 20227/71 Heading C7F In a process for vacuum deposition of metals or metal compounds on substrates in which the vapour is produced by electron beam heating, the vapour density of the metal or compound is varied by a varying programmed control input superimposed on a basic input to vary the energy or intensity of the electron beam so as to achieve a specific rate of growth or layer structure of the deposit. As shown, Fig.1, a vacuum vessel 10 encloses a substrate 13, a crucible 11 containing a metal 12, such as palladium, to be evaporated, an electron gun 16 and a probe 22 connected to current measuring instrument 24. Basic input to the gun is supplied from high-voltage D.C. unit 18 by way of coupling element 19. Variable input is supplied from source of potential 21 through a programme controller 20 to the coupling element 19. The input is varied to compensate for undesired variations in vapour density due to adventitious fluctuations in the conditions by measuring the ionization current from probe 22 and applying this current to a regulator 25. When depositing palladium, the course of deposition may be controlled to give a layer of high internal stress which cracks on cooling giving a deposit of large surface area useful as a catalyst, or to produce deposits of low stress and good adhesion for use as mirrors. The deposit may be formed of two different materials evaporated from separate crucibles, one being deposited at constant vapour density while the vapour density of the other is varied.
